CVE-2026-74439

CVE-2026-74439 affects the Linux kernel IOMMU VT-d path. The vulnerability arises in device_pasid_table_teardown(), which zeroes a 128‑bit scalable‑mode context entry while the Present bit is still set. This creates a window where a torn entry could be fetched by the hardware with some fields alr...
